The best cheap eats in every state: Portland Penny Diner

"Despite all the cheap eats Portland has to offer, [writer and Cooking TV host Ali] Khan's favorite is the PDXWT at the Portland Penny Diner, which is located inside the Hotel Lucia. For under $6, diners get a platter that includes mortadella, sauerkraut, egg, and cheese, served on a Parker House roll. "What will really catch your palate is the coffee mayo, which could easily be renamed espresso cream spread and still nothing would be lost in translation," Khan said.
